This invention relates to a machine for printing value. stamps in which the printing roll is connected with counting mechanisms.

` In counting and printing apparatus of known type rolls or disks are used as carriers for the several values, and these value cai'- riers are designed each for a single value or each for several diferent values, the stamps printed being recorded by a counting mechanism merely as regards number without consideration of the value of the stamp which has been printed.

With the apparatus of known construction it is further not possiblev to divide a single value carrier into sections which are designed each for a stamp of different values so that every succeeding division of the roll or lprinting cylinder is designed for a stamp of twice the value as the preceding stamp or of a value which is increased at a determined ratio. None of the apparatus of known Atype comprises a device which permits to ascertain how much of a predetermined amount of value has been already spent or which amount is still at disposal. l

This invention has for its object to arrange on a printing cylinder any number of stamps of different values. The values are doubled or increased in any other proportion by means of a reversing device and adjusted so that they are ready for use. The stamps which are being printed are at the same time registered not according to the number but to lthe value so that the total value of all the stamps which have been printed isprinted on the paper together with each individual stamp, only one counting mechanism being required. n n

In conformity with the-carriers of the value stamps the feeding devices for operating the counting mechanism can be also increased as regards value simultaneously with the valueincrease of the stamp carriers, a common shaft being used for these two adjusting operations.

This is effected with the aid of a novel feeding' devicel which produces the changes according to the shape of the links of chains with feeding teeth alternating with the gear Vof feed wheels, the reversing of the value same with reference to the two forms of -construction according to the accompanying drawings, wherein l Fig. 1a is a side elevation partly in section.

In the hollow printing cylinder a the valve stamp e is located and keyed upon the shaft so that it participates in the revolution of said shaft, the value stamp e can be either of circular cross section or of prismatic cross section and is engraved upon its circu1nference or upon the several faces with matrices for stamps of various values and kinds, for instance postage stamps, insurance stamps, revenue stamps or similar indications.l The printing cylinder a; is keyed upon the shaft c. Upon the right hand side end of shaft a toothed wheel d is keyed which is held in the adjusted position by a locking pawlg controlled by a spring g. A toggle lever z' may be connected with the supports f so that the printing cylinder e is lowered and brought in contact with the surface upon which the stamp has to be printed, in the manner described in a parent application, by thev depression of the toggle lever z'. The toggle lever z' is merely diagrammatically shown as its construction and operation are fully described in the parent application. The shaft c mounted in the supports f so thatit can revolve carries the hollow shaft /L which is movable in lateral direct-ion. Upon this hollow shaft 7L spur wheels h and are keyed. A pressure spring t wound around said hollow shaft k inside the drum a serves for bringing lthe spur wheels h and the adjusting disk t', keyed upon the hollow shaft, in engagement with the feed disk u arranged upon the shaft 0. This feed disk u has in its inner hollow space adjustable feed teeth 'v which project through the circumference of the disk. Upon the end of the hollow shaft L which projects from the casing A a handle B is arranged which is controlled by a spring c. The handle B is hollow and encloses the spring lc which is wound around the shaft h and fixed on the saine. Upon the outer sur"- face of the wall of casing A a stanshaped disk m is fixed with the spaces m between the teeth of the same the fork m of the handle B engages through the action vof spring 7c which bears against the wall B of handle B so that'the accidental rotation of the handle is prevented. Marks or figures 10, 20, 30 are arranged over each notch m which indicate the stamp value in accordance with t-he stamp values marked upon the printing cylinder e.

Upon the, left hand side end of shaft c a spur wheel n is fixed on the drum @which meshes with a spur wheel n2 keyed upon a shaft n. The shaft 'n' mounted in the sup- I port f carries further upon its other end a counter feed disk 0. At the side of this counter-feed disk is a hollow shaft o is adjustably mounted upon the shaft n and carries a toothed-wheel p. As shown in Fig. 3 the spring p bearingon axle 0 and on the other hand on support f presses into engagement with the feed disk 0 the adjusting disk g, rigidly connected with the toothed wheel p. The feed disk o has various teeth, incisions or angular pieces 1U upon its circumference of which, according to the adjustment of the handle B and in consequence of the form of disk y similar to a sector Fig. 4, a determined number are made to roject from the circumference of the feed disk o. The number disks of the counting mechanism s are arranged upon the shaft 7' mounted in drum a and said disks are operated by the feed teeth o as, at the rotation of the drum a the feed wheels s for the counting mechanism s mounted on shaft f1' rolls around the stationary feed disk u so that it is acted upon by the feed teeth 'u and operates the counting mechanism s.

The operation is as follows Suppose the printing cylinder e has to be adjusted for the printing of a total amount of stamps of a predetermined value. `With this object in view the fork m is withdrawn with the aid of the handle B from the notches m of the star-shaped disk m the hollow shaft h with the spur wheels L and [t2 being pulled back at the same time. The spur wheels L and 71.2 are thus brought into engagement with the toothed wheels l and p respectively. At the same time the end face of spur wheel h acts upon the extension y of pawl. g and disengages this pawl from the toothed wheel d. By the rotation of the handle B together with the hollow shaft l1, the printing cylinder e is adjusted through the intermediary of toothed wheels h and d to the desired value degree. By the simultaneous bringing in gear of the spur wheel h2 with the toothed wheel p a number of the feed pins w and fv of the feed disks o and u corresponding to the value degree in question are made to act upon the counting mechanisms through the'intermediary of the adjusting disks g and t. If the adjusting is finished and the handle B released the hollow shaft h and with the same the spur wheels h and h2 are returned to the initial positions by the action of the spring k. At the rotation of the spur wheels p,

the drum a around the stationary shaft() and at the printing of a stamp by the printing cylinder e the same value as printed is recorded in the counting mechanisms.

By thes'purwheel 1|, keyed upon shaft c outside the drum a and meshing 'with thespur wheeln'z keyed upon shaft n', the feed disk o is made to revolve at each printing of a stamp owing to the rotation ofI drum a, Iwhereby the feed teeth w operate the feed mechanism of a counting device which, according to the adjustment of the printing cylinder e is fed by the teeth to for the amount of the value of the stamp for which the apparatus has been adjusted. l The counting mechanism operated by the drum in synchronism with the above mentioned counting mechanism records also the value of the different stamps`` printed and prints further upon the surface the actual state of the total amount of the stamps which have been printed. The printing roll e prints its stamp at the side of these records.

Fig. 5a showsa moditied construction of the releasing device B which consists in this case of a handv lever a pivotally mounted at on the support f and enzbracing the hollow shafts o', la. upon which shafts the spur wheels p, h2, h are keyed. vThe hand lever a and the spur wheels 3),'h2, 7i are held, by the springs u in the normal position of rest, or in engagement with the counter feed mechanisms 0 and u. If the lever e is moved to the right for the' adjustment of a stamp value h2 and h and l are brought into gear in a similar manner as above def I scribed. The adjustment of the feed teeth fw, c and of the printing roll e is efected from the adjusting united to form a ring Okeyed upon the shaft 0.` The adjusting arms B have marks or figures 10, 2O and so on upon their heads. After the adjustment all these` parts return, under the action of the springs, to the initial positions.

Referring Figs. 1 to 19 the casing of the rolling stamp. is composed of two parts X and Y. The part X has hooked-shaped catches 12 (Fig. 7) with whichthe hooks 21 (Fig. 1) of the part Y of the casing in which the entire driving mechanism is mounted engage if the two parts 'of the casing are put together. The driving mechanism for the printing cylinder consists of vtwovstanda-rds 31 and 31 (Figs. 1.l 2 and 3) which are connected with one another by an intermediary piece 32 with connecting screw 34 (Fig. 1). The standard 31 rests upon the part Y of the casing and the rail 31 engages with the guide piece of the part X of the casing if the two parts of the apparatus are being put together (Fig.

-In order to further secure the support in its positiomthe standard 31 bearing against the part Y of the casing has a projection 33 which arms B which are4 to the construction shown in' is locked in a notch of the part X of the casing, so that a variation of the position of the -supports for the ldrive is securely pre-v vented.

The printing cylinder d (Figs. 3, 5 and 6) which is constructed like a capsule 46 is closed by a lid 47. Locking screws 48 (Figs. 5, 6) serve for connecting the capsule and the lid. `In the capusle 46 of the printing cylinder d two counting mechaninsms 60 to 66 for the stamps printed two mechanisms 91 to 97 for adjusting the stamp values and also the device for altering the stamp value are arranged. The printing types of the counting mechanisms for the stamps printed and of the adjustingdevices foi-the stamp value project through the opening in the' wall ojt' j feed wheels 65 and 66 of different diametersv which have a determined ratio of division the one with regard to the other. These feed wheels 'feed the counting mechanism. according to whether the larger wheels 65. or the smaller wheels 66 are operated with the same times of revolution, either for the normal amount of numbers or for the double amount. rfootbed locking disks 6) connected with the top number disk 61 are also mounted upon the same shafts 62 upon which the wheels 65, 66 are keyed. Blade springs 67 slide one upon each of said locking disks (Fig. 5) in order to regulate the uniform revolution of the figure wheels, said blade springs being4 mounted upon hollow axles 68 telescoped upon the driving axles 64.

The driving ofthe wheels 65, 66 is effected through the intern'iediary of the driving wheels 110 of the counter. Upon the sta tionary axle 49 of the stamping roller a cas` ing 71 for a tooth chain is fixed by means of studs 72 or teeth 77 whichv in each half of the casing are combined to form a chain 76 proj ect through slots 74 and engage with the drive wheels v110-which control the counting mechanisms of the counting mechanism. The

the like (Figs. 6a and 6b). The

- the stamps The axles 92 of Vspend with the value of the which it is connected by a hinge pin 78 so that the teeth 77 are united to form an articulated chain 76. A hollow axle 80 is mounted on the shaft 49 (Figs. 5, 6, 6- and 18) and upon the part of this hollow axle which terminatesl inside the casing 71 for the tooth chains, the eccentric 79 is keyed. The faces 7f of the eccentric 79 are, at the po-. sition of rest, out of contact with the two chains 76 but if the eccentric is being operated, a number of teeth 77 are advanced through the slits of the casing which correstamp for which the apparatus is adjusted so that these teeth are securely held in this position. Two'locking faces for the counting mechanism of printed are arranged on the periphery of the casing 71. rlhese locking faces 7 5 bear at the moment of the printing, or in any other desired lposition of the printing cylinder, against the locking disks 69, whereby the accidental or intentional rotation)of the figure wheels is prevented (Figs. 5, 6. v

For each counting mechanism of the stamps printed a corresponding mechanism for the adjustment of the stamp value is arranged. The stamp value rollers 91 (F igs.` 5, 6 and 17) serve as carriers for the several stamp values which can be provided in any convenient manner. The surfaces of these rollers 91 are divided into asmany sections as stamp values are to be provided. One group of'stamp values can for instance comprise the numbers 1-10, the next following group the numbers 11-20 and the third group of numbers 21-30. According t-o whether the one or the other of the groups of stamp values are adjusted for operation, numbers of a higher or lower value will be printed. the rollers 91 are journalled in the walls 46, 47 of the printing cylinder al. Upon each axle 92 a toothed wheel 94 is keyed which serves as drive (Fig. 17 A spring 95 mounted upon the corresponding axle 92 (Fig. 17) serves for regulating the uniform rotation of the stamp value rollers'91 by sliding upon the bottoml surface -of the capsule \46 so that at the adjusting of the rolls 91 the centrifugal action of said rolls is braked. After the stamp value rollers have been adjusted for a determined number they are locked in their position by means of a locking member 97 (Figs. 5, 6a and 18) rotatable around the shaft and having locking claws 97 teeth ofthe drives for the stamp value rollers.

)Vith this object in view thelocking member 97 is teleseoped on shaft 80. f Its ringshaped bush, constructedl to form a bearing surface, is rotatably mounted on the feedwheel 82 and the locking claws 97 engage with the toothed vwheels 94. If the member d revolves the locking member 97 participates in this revolving movement revolving designed to engage with the' in its ring-shaped bush rotating above the stationary adjuster 82 supported by the toothed wheels 94. If the rollers 91 marked with the groups of stamp values are being adjusted, the locking member 97, which is situated directly above the adjuster 82 must be raised together with this adjuster which is raised by shaft 80 so that the claws 97 get out of engagement with the toothed wheels 94. `If the adjuster 82 returns to the position of rest, the locking member 97 with the claws 97 is broughtback to the initial position by the action of the springs 95 mounted on the axles 92.

Upon shaftA 80 the adjuster 82 (Figs. 5, 6, 18) having a toothed segment 82 is keyed which serves for rotating the rollers 91 so thatthey print a stamp of determined value.

The simultaneous adjustment of the feeding devices for the counting mechanisms so that they correspond with the stamp values adjusted is effected by a reversing device. Between the capsule 46 and the lid 47 the reversing axle's 109 are mounted upon which the toothed driving wheels 110 for the counting mechanism are keyed (Fig. 6a). Upon the guide face 109 of the axles 109 fiattened above the wheels 110, reversing wheels 110 and 111 (Fig. 19) are mounted which are adapted to be raised and lowered and which stand the one over the other (Fig. 19). Reversing forks 106 of the reversing lever 106 (Fig. 5) engage with the guide collars 113 of the guide bushes 113. The reversing lever 106 rests with its bearing face, on the one hand, upon the ringsha-ped bearing 115 of the shifter 115 and it is mounted on the other hand with its guide bushes 108 in the columns 107 arranged between the capsule 46 and the lid 47 so that it can be moved in vertical direction (Figs. 5 and 18). The shifter 115 is adapted to be displaced in lateral direction between the segments 81 upon the adjusting shaft 80 (Fig. 5). Upon the extension 33 a curve-ring'117 is arranged (Fig. 14) against which the curved member 116 revolves, this member being removably fixed upon the shifter by means of screws. ...Upon the part of the adjusting shaft 80 which projects from the wall of part g/ of the casing the adjusting lever 124 is fixed by means of a stud 118 or the like (Figs. Sand 12-14). The handle 124 of the adjusting lever has a hand 124 vwhich lmoves over the notches 127 of the adjusting scale 126 fixed by screws 126 upon the casing y said notches 127 indicate each a determined stamp value. Upon'the .plate 35 a base plate 143 is fixed for a counting mechanism (Figs. 1, 2, 11) which is visible and is fixed by means of screws so that it can be easily removed. In the. casing 136 of the counting mechanism the ligure wheels 137 which are operated in the well known manner by feeding pinions revolve around'the ing mechanism a casing shaft 140 which in its turnis driven by the toothed wheel 141 (Fi 1).

For the object of fee ing the visible counti 152 for a tooth chain is fixed by means of a screw 153k., or the like upon the shaft 151 journalled in the members 31, 31 (Figs. 1, 3,- 9, 10, 15, 16). The casing 152 has four slits in its surface Vof which two are juxtaposed in each half of the casing.

` consequently of v 151 by means of l ing the eccentric a bearing block,

" the locking scale 175 has The teeth 157 of the chain which have i'n the manner above describedleach a fork 159 and a hinge pin 160 project also through these slits 154, the chain 155 carrying double the number of teeth 157, 157 as the chains 156. An adjusting eccentric 162 connected with its support 161 movably mountedupon shaft 151 is pushed into the casing of the chains and serves for closing said casing by its rim 162. Shaft 151 is enclosed in a sleeve 161.` A pressure spring 163 bears against the closing disk 161 keyed on sleeve 161', and fixed on shaft a pin 151', said spring press- 162 into the chain casing 152 and ensuring thus an always uniform mounting of the same. The rotation of shaft 151 and the visible counter is edccted together with the movement of the printing cylinder d by means of the toothed wheel 164 mounted upon this roller and participating in the movementI of the same and further by means of the counter toothed wheel 165 meshing with the toothed wheel 164 and securely coupled with shaft 151 (Figs. 1, 5, 6). For limitino' the working of the counting mechanism aocking device is used in the well known manner (FigsV 1, 2, 11). Upon the plate 143 (Fig 1) the angle iron 171 is arranged. In the arm 71 opposite to the fixing point and forming an axle 172 is journaled upon which the angular toothed wheel 173 is mounted by means of a stud 173 or the like (Figs. 1, 2, 11) the teeth of this angular toothed wheel meshing constantly with the toothed wheel 138 of the extreme figure wheel 137. The axle 17 2 is further journaled in the angle iron 174 fixed on plate 143 and embracing shaft 140. Above the angular wheel 173 the locking disk 175 with the locking scale 175 is connected by a pin or the like with the locking shaft 17 2. Over this locking disk 17 5 the carrier 177 for the locking lever is mount ed upon shaft 17 2 so that it can be displaced in upward and downward direction. The carrier 177 carries at its lower end the locking lever 177 adapted to engage with the corresponding locking notch of the locking scale. The carrier 177 is guided at its head 177 and it is held by means of a pressure spring 178 located in the hollow carrier 177 and wound around the shaft 17 2 so that the locking lever is secured in its engagement with the corresponding notch.

After the amount of stamps determined by been printedl the the .entire feeding device for locking lever acts upon the locking lever 186 for the driving gear (Figs. 1 to 3). Upon the intermediary'piece 32 the bearing confisting of an angle piece 187 4for the lever 186 is arranged the journal 190 of which revolves in the upper-piece 187 and is connected at the middle with a lforkfshaped connecting lever 192 the perforatedfork-shaped ends 192 of which embrace on the one hand the locking lever 186with which they are movably connected by screw 193 or the like, and on the other hand the angular abutment 195 with which they are hingedly connected in a similar manner by a screw 194 or the like. The angular abutment 195 rests with its bearing surface which forms a bearing column 195 and with journals 195 in the connecting piece 32 so as to form a double angulary bearing.. The locking lever 186 acted upon by the locking lever 177 of the .counting mechanism places itself with its angular abutment 195 in front of the locking flange 198 for the driving gear keyed upon an extension vof the counter toothed wheel 165 (Fig. 9), a stud 198 or the like ensuring the connection between the locking flangey 198 and the counter toothed wheel 165. The pull spring 197 wound around the angular abutment l195 and fixed upon the double angle piece 196 by a stud 197 or the like serves for returning the lockinglcver 186 from the locking position into the position of rest.

The uniform rotation of the several stamping faces ofthe printing cylinder is en sured by a regulating device (Figs. 1 to 3). Upon the inner side of the part X of the casing atthe left hand side in front of the printing cylinder a sliding rail 211` is arranged in which a sliding carriage'213 is mounted which is adapted to be displaced in upwardk and downward directions. A guiding lever 2,17 is mounted upon the journal 218 fixed upon the sliding carriage 213, one end of said lever forming a locking abutment 217. A spiralspring 219 held at one end by a pin 219 or the like engagesiwith its other end the guide lever 217 and'forces the sameinto the initial position limited by the stop pin 220 of the casing y. Upon the guiding the rail 211 a supporting piece 221 is arranged and fixed by means of a screw 222. This support 221 has a pin 227 around which the lever 224 oscillates which has an extension 225. A pull spring 228 is attached on the one hand to a pin 226 fixed upon the angle lever 224 and on the other hand to a pin 230 fixed at the upper end of the carriage 213. The carriage 213 supports in its part which projects through anaperture d at the lower end of the apparatus upon a journal 216 a revoluble wheel 215 which, if the apparatus is 'placed upon the surface to be printed, raises the carriage. The printing jcylinder d has locking pins 53 on the lid 47.

In order to ensure that the mechanism can be` adjusted from one stamp Value to the other only after one stamp has been completely printed a special device is provided which consists of a locking pawl A214 mounted upon the carriage 213 which pawl slides over the rim of the lid 47 of the printing cylinder d when this cylinder is rotated and engages under the action of spring 228 within a corresponding notch 52 (Fig. 1) only if oney rotation of the cylinder has been completed. The back rotation of the printing cylinder d and consequently a fraudulent re-using of the stamp which has already been printed, is prevented by a device which locks the cylinder al against back-rotation (Figs. 1 to Upon the connecting piece 32 a locking tooth 246 Ahaving two noses is fixed by means of a screw 248 and pressed by the action of a pressure spring 249 between the teeth of the counteractuating toothed wheel 165 so th at it prevents the backrot-ation of this wheel. The inking of the printing cylinder d is effected by an inking device (Fig. 7). With this object in View acasing 256 is arranged on the front face of the apparatus and an ink tube 258 is arranged in said casing which ink tube has nozzles and is surrounded by a number of juxtaposed lamellen 259. An inking ribbon 261 is placed upon these lamellaa. A locking wheel 264 is arranged around the inking tube 25S. A locking pawl 265 has a nose 265 which engages with the locking wheel 264. At the upper part of the casing 256 a lever 265 is pivotally mounted by means of a screw 263, a screw 267 serving to tix the lower part of said lever. gaging with a nozzle 267 and also with a nipple 263 of lever 262 serves to pull said lever 262 downward so that it bears against the inking roll andpresses the same against the printing cylinder d. Behind'the printing cylinder d the lower part of the wall of the casing X is bevelled in order to prevent that the stamps printed be blurred when the printing cylinder is rolled over the paper. The printing cylinder is protected by a closing ,device (Figs. 1, 3, 7, 4). A T-shaped double angle 295 is pivotally mounted upon a pivot pin 296 of the part X of the casing and has in its head a guide screw 297 which projects through a slit 297 of the part X of the casing and has an extension 297 provided withan eye which grips at the closingposition over the closing cramp 15 into which a padlock or the like can be inserted. The double angle 295 has upon its lower arm a guide pin 298. A supporting lever 301 is 'mounted with both` arms 301 upon the axle 151 and movably connected by means of a connecting screw 300 with 4the transmission lever 299, the .slot 299 of which serves for receiving the guide pin 298. The straight armv ci the transmission lever 299 is also movably mounted by means of a screw 303 in a supporting wall 302 of the locking bow 302.

A spring 266 of lever 265 en-l The two supporting walls 302 are terminated by lugs 302 by means of which they are suspended upon the shaft 49 and 80 so that the bow-shaped part 302 encloses part of the printing cylinder d.

Theoperation is as follows z- Suppose the printing cylinder has to print a stamp of the value 50. shaft has to be pulled out by means of the handle 124 so far that the value indicating hand 124 may be turned up to the notch 50 to be inserted in the same. Vvlhen the shaft 80 is being pulled out the claws 97 of the locking member 97 are at the same time lifted out of the pinions 94 of the value rollers 91 and the toothed segments` 88 of the feed wheel 82 are brought into engagement with thc pinions 94. The feed wheel 82 mounted upon the shaft 80 participates in the revolution of said shaft and adjusts the value indicati ng rollers 'connected with it by the toothed wheels 94 to the figure corresponding with the value 50. At the same time the feeding devices for the stamp counting mechanism are adjusted. The eccentric 79 at the end of the shaft 80 is thus made to act upon the different teeth 77 of the toothed chain 76 and if one tooth advances at the feeding with one number in the counting device. it must push through the slits 74 of the casing a number of teeth correspcndingto the adjustment, in the present case tive teeth. The stamps produced bythe apparatus must however not print only the actual value and the number of the stamps which have been printed or the total value of these stamps but also the printings must be further visibly recorded with the aid of one or severa-l counting mechanisms. The counter 136 with driving pinion 141 is for instance provided for the visible recording of the total value of the stamps which have been printed, the indications of this counter 136 appearing in a window. The driving wheel 141 keyed upon shaft 140 is driven b a feeding device 151-161 which'is mountec in the casing 152 of the tooth-chains 155 and 156 and the eccentric yof which acts upon the tooth chains 155, 116 in the mannerV as described with reference tothe feeding device 71-82 for the counting mechanism for the stamps printed. The adjustment of this device for the visible counting mechanism is effected from the shaft 80 at the same time as the adj ustment of the feeding of the counting device and of the rollers 91 for the values printed. With this object in view a toothed wheel 119 is arranged upon the shaft 80, which7 by the intermediary of the toothed wheel 121 mounted upon the standard 31 operates the toothed wheel 1 23 connected with the eccentric 162 (Figs. 1, 3, 9). According to the`adjustment on the adjusting scale 126 the eccentric 162 will be revolved by the toothedwheel 123 so that its rim 162 slides relatively to the casing 152 and brings thcorresponding num'ber In this case the.

of teeth 157 and 157 into engagement with the driving gear for the visible counting device by making the same project through the slits of the casing 154. The pressure spring mounted in the support 161 of the eccentric maintains the eccentric constantly in proper position in t-he casing. The number of the teeth in the casings 71, 152 for the tooth chains can be arranged as desired. The possibility to increase the effect of these teeth if the same number of teeth are used is provided by the arrangement of a scparateadjusting device. In this case the effect of each single toot-h is for instance increased in` such a manner that the tooth counts, owing to the adjust-ing device for two figures. In the form of construction shown by way of example the adjusting device is constructed as follows z*- If the adjusting eccentric 79 has advanced all the teeth 71 in consequence of the handle 124 having been operated for the lowest group of values, said eccentric at the adjusting for the neXt higher group of values,

will be brought out of Contact with the toothl chains by a further rotation ofthe shaft 8O and moved to the first tooth of the second tooth chain in the casing 71. Simultaneously the toothed segments 82 of the feeding wheel 82 of the stamp value indicator have at the rotation of shaft 80 got outof engagement with the driving 'wheels 94 of the value roller 91 and after the idle movement caused.

by the part between the two toothed segments 82 the -first tooth of-each toothed segment 82 is ready again to act upon the feeding wheels 94"after, by the last tooth of each toothed segment S2', he rollers 91 1nave been revolved so that they indicate the next high-- er value group. At this idle running of the adjusting eccentric 79 from one tooth chain `to another as well as of the feeding wheel S2 theadjusting cam 116 which is fixed upon the shifter 115 moving between the guide segments 81 of shaft 80 has moved over the' ascending curve formed by the counter-ring 117. As the adjusting cam 116 is fixed upon the shifter 115 andas the counter-ring 117 is fixed upon the shoulder 33 of the bearing, the shifter 115 must at the ascension of the cam displace itself outwardly so that it lifts by means of its ring 115 the lever 106 (Figs. 5, 6). The two forks 106 of the lever. 106

embrace in thel guide slots 113 the guide bushes 113 of the large wheels 112 and of the small wheels 111 mounted upon the axles 109 lifting the small wheels 111 out ofthe large feeding wheels 65 for the counting mechanism and bringing the large wheel 112 into engagement with the small feeding wheel 66 of the counting mechanism.

Before the adjusting'the wheel 111 was in gear for the feed wheel 65 of thecounting mechanism. If in this position the printing cylinder d has been revolved through the intermediary of the shaft 49, the toothed wheel 110 would havebeen rotated by the teeth 77 when passing along the stationary casing 71. The toothed wheel 111 mounted on the same'shaft 109. as toothed wheel 110 transmitted its movement upon the toothed wheel 65 which'in its turn operated the counter 61 for the printing operations. The

toothed wheel 111 has with regard to toothed wheel 65 such a ratio of division that each movement caused by one tooth through the in gear with the toothed wheel 111 of the same ratio of division but the large toothed wheel 112 is in gear with the small toothed wheel 66. The ratio of division of these two wheels 112 and 66 is such that the rotation of wheel 110 effected by one tooth 77 produces, owing to Jthe altered ratio of transmission for the same time unit, a movement of toothed wheel 66 for the double amplitude and consequently the advance of the number disk of the lowest value in the counter 136 for two figures. i

The feeding device for the mechanism for the visible counting may also be adjusted for the inci/'eased action of the feed teeth, this being effected either in the manner vwhich has just been described or by mountingin the casing 152, besides the two tooth chains 156 with normal feeding effect of which one tooth 157 of each chain serves to advance the counter 136 for one figure7 two toothed chains 155 with a double number of feeding'teeth 157. The arrangement of the tooth chains 155. 156 is in this case so that in one half of the Vcasing 152 the normal chain 156 is mounted upon the inner wall, and the double chain 155 upon the outer wall and that in theI second half of the casing the normal chain 156 is mounted upon the outer wall and the double chain 155 upon the inner wall. The chains are therefore displaced in both halves of the casing the one withA regard to the other. The two eceentrics 162 in the casing 152 are also mounted upon the support 161 displaced the one with regard to the other. Each eccentric can operate in one half of the casing only-the-one, the simple chain 156, or the other, the double chain 155.

j wWhen the shaft S0l is pulled out by means of the handle 124 for adjustment the tooth wheel 119 keyed on said shaft comes in gear with the toothed wheel 121 which is loosely mounted on a shaft 122 and which is permanently in gear with the toothed wheel 123. By the putting in gear of toothed wheel 119 these threeltoothed wheels 119, 121 and 123 are connected the one with the other to form one gear. If the handle 124 is now turned, which means that it is adjusted forone value group, the toothed wheels 119, 121 and 123 net are rotated at the same time so that toothed wheel 123 drives the eccentric 162. The ratio of transmission of these three toothed wheels is arrangedl so that in accordance with the value group adjusted on the value roller 91 the required number of teeth 157 or 157 are made to advance through the slits 154 of casing 152 by means of the eccentric 162. The teeth 157 will then rotate each for one figure through the intermediary of pinion 141 the number disk of the lowest value of counter 13G. At the transmission of the value roller 91 to a higher value group the eccentric 162 has evidently participated in the rotating movement transmitted by the toothed wheels 119, 121, 123. At this occasion the eccentric 162 has gone away from the simple chain 156 and comes in engagement with the double chain 155 in the other half of the casing 152, so that the eccentric will now make advance along a `double tooth 157. of chain 158. One double tooth 157 veffects however the advance of two figures in the counter 136, so that in conformity with the adjustment of tlie-counting mechanism for the stamp printed the effect of the visible counting mechanism is correspondingly increased. At the reverting to .the normal action of the teeth the simple chain will be put again in gear in the visible counting mechanism and in the countingmechanism for the stamp printed the descending cams .116, 117 will push the shifter 115 back into its initial position.

At the same time the large reverting wheels 112 of the feeding gear for the counting mechanism for the printed stamps disengage from their pinions 66 and the small reverting wheels 111 are brought again in engagement with their pinions 65. It is evident that by modification of the ratio of transmission of the driving wheels 65, 66, 111 and 112 with regard to one another any increase of the effect of the existing feeding devices can be produced. V

If now the printing cylinder, after the feeding devices have been adjusted rolling on the stationary shafts 49, 80, there are printed, besides pictures, figures or number which on the value roller 91 indicates the value of the stamp and further from the counting mechanism 61 the total of the stamps which have been printed. If the printing cylinder prints for instance postage stamps and if the post oflice which lets the apparatus has determined a limit amount for which stamps can be printed, the post office can see from each has been used of the amount. This control is very useful for the post .oice prepaid total as well as for the use of the apparatus. During the revolving of the printing cylinder the driving wheels nism move over the adjusted teeth7 7 projecting from the stationary casing 71 on axle 49,

inscriptions, the

printed `stamp how much' for the counting mechaare advanced by the same and operated by their reverting wheels 111 or 112 the feed wheels 65 or 66 of the counting mechanism. These feed wheels rotate in the well known manner through the intermediary of the pinions 63 mounted on the axles 64 the number disks 61 in accordance with the number of the adjusted teeth. After the feeding, the locking disks 69 ,connected with the upper disk 61 slide upon the locking faces 75 and prevent thus the rotation of the number wheels 61 (Figs. 5, 6, 6a). The toothed wheel 164 fixed upon the printing cylinder d revolves with the same and engaging with the counter toothed wheel 165 keyed upon the shaft 151 makes this shaft revolve so that the teeth 157 or 157 of the casing 152 are made to operate also the driving gear 141 for theI visible counting mechanism 136.

As previously described the visible counting` mechanism has in the well known manner a locking device which locks the counting mechanism as well as the driving gear connected with the same as soon as any determined number is reached.

In the course of the printing the device 141 is rotated by the-teeth 157 or 157 and the number disks 137 are rotated or advanced in the manner known from counting mechanisms. lVith the number disk 137 which has the highest figures a toothed wheel 138 is connected so that it rotates with the same. In the formof construction shown in Fig. 11 the number disks 137 serves for the thousands.

If in course of the printing this number disk 137 has rotated for one figure the angle wheel 173 which is in permanent gear with toothed wheel 173 is rotated as well as its axle 172. In this-rotation participates the locking disk 175 keyed on axle 172 and the lockin lever 17 2 of the same. This locking disk 1 5 has ten notches 17 5Jwhich means that the locking disk 175 is divided into ten units in a similar manner as the number disk 137 a-nd that each notch 175 from 0 to 8 corresponds with one' figure ofthe number disk 137 said locking disk 175 being thus rotated in accordance with the number disk 137 for one unit of the thousands. If in course of the printing the counting mechanism arrives at the predetermined lfigure at which the apparatus and the counting mechanism have to be locked, the lever 177 engaging with the scale 175 acts upon the lever 186 designed to lock the driving wheel 165.' If the locking lever 177 has for instancebeen made to engage with the number IX of the locking disk 17 5, as shown in Fig. 2, it must operate the lever 186 at the instant when the number disk 137 is revolving from figure 8 to figure 9, that is to say from number 8000 to number 9000.

- The lever 186 pushes with the aid of the connecting lever 192 fixed upon it the angular abutment piece 195 pivotally mounted in a column-bearing 195" into the path of the locking flanges 198 which turn together with the toothed wheel 165 around the axle 151 and are locked by the angular abutment 195. After the 'locking lever 177- for the counting mechanism has been released from its locking position Vin the form of construction shown from notch'IX the locking lever 186 for the drive gear returns under the action of the pull spring 197 to the initial position and. releases thus the locking flange 198 and consequently the driving gear. Owing to the locking disk 175 it is possible to extend the locking limit to a desired value before the locking of the counting mechanism begins so that it is not necessary to wait for the locking taking lace before the locking device can be re-a justed. j

The person who uses the apparatus can read from the counting mechanism 136 the actual state of the value of the stamps printed but he cannot ascertain how many stamps can still be printed. The following device serves to obviate this inconvenience i The head 177 of the support for the locking lever of the locking system for the countin mechanism carries a mark 176 (Fig. 8). Around the head 177 projecting through an aperture of the lid 6 of the apparatus a circle of figures from 9 to V0 (Fig. 8) is arranged upon the upper surface of the casing X and 230 (Figs. 1,

the head of' the support of the locking lever rotates in this circle simultaneously with the locking disk 175 so that the mark 176 indicates always the number which corresponds with the total value of the stamps which are still to be printed.

In the example shown in Fig. 2 the lever 17 stands over the figure IX as the number at which the apparatus has to be locked. Suppose the vnumber disk 137" has just moved from 7 to 8 or from 7000 to 8000; in this case stamps for the value printed before the apparatus is locked. This ,is indicated by the mark 176 pointing to 1 which is equal to 1000. `When the number disk 137 has rotated tothe ligure 9=9000 this mark 176 will point to 0 in the indicator 2 indicating thus that the amount for which the apparatus has been adjusted is exhausted.

The several stamping faces of whichy any number can b'e arranged'upon the printing cylinder cl are limited by alocking device 211,

The several sections upon the surface of the roll 0l are limited by the stops 53 (Fig. 6) arranged upon the capsule 47. When the apparatus is being placed upon the surface to be'printed, the wheel 215 raises the sliding carriage 213 connected with" the same and moves the guide lever 217 ofl said carriage towards the locking lever 224. Shortly before a division of the surface of the roll d has ,inder d the stop of 1000 may still be` of the @over ,abutment 217 to be finally pressed against this abutment by the stop 53. The stop 53 is now prevented from oscillating the lever 224 around its axle 227, the stop 53 being thus arrested so that the printing roll d is locked against revolvingafter the division has been completely printed.

lVhen however the apparatus is lifted olf the surface to be printed the wheel 215 looses' its support and the, sliding carriage 213 returns" with its guide lever 217 to the initial position under the action of the pull spring 288. At thesame time the guide lever 217 is swung backby the action of spring 219 into the position of rest limited by stop 120. At the renewed operation of the printing cyl- 53 which has previously stopped the movement of the roll can now make the lever 224 oscillate from its path so that it can pass along this lever. The lever 217'has not been acted upon by the stop 53 this time so that it is still in'its position of rest outside the path ofthe stop 53 and of the abutment 225.

The locking pawl 246, the locking noses 246 of which engage with the teeth of thetoothed wheel 165, prevent the back rotation of the printing cylinder and consequently also the repeated use of the stamping faces without registration of this use. A safety device prevents that, after the printing of the stamp, the feeding devices for the counting mechanism are adjusted fraudently to a lower stamp value than at the beginning of the stamping. With this object in view a locking pawl 214 is arranged at the upper end of the 213, said pawl slid'ng upon the rim 47 (Fig. 1); The carriage 213 is thus lifted always so far that part of the carriage and of the running wheel 215 stands between the driving wheel 119 and the wall of the casing y. s It is thus impossible'to displace the shaft laterally together with the adjusting lever 124. Only if all the stamp faces have been used the locking pawl 214 descends and engages with a locking notch 452 o\f the rim of cover 47 At the same time the carriage 213 and with it the running wheel 215 are lowered by the action of spring 228 for an amount which is equal to the depth of the locking notch. The driving wheel 119 for the adjustment is thus released by the carriage and by the running wheel and the adjusting toa new amount of stamping values can be effected. Y

. The inking of the printing cylinder d is eected from the inking roller 261 which is pulled against the printing cylinder d by pull strings 266 acting upon carriage 224 lwhich lever is the levers 262 1n l rib which said ink-holder is mounted. Around the ink-tube 260 which has the nozzles a desired number of lamellae 259 are arranged, between which the ink is stored which has been filled into the-ink tube. An inking ribbon 261 encloses the lamellae so that only so much .ink is uniformly transmitted by the bon as is used by the printing cylinder d. If the casing 256 of the inking device is being removed from the apparatus, the locking pawl 265 slides olf the rail 18 and engages under the action of a spring 266 automatically with its tooth 265 in an indentation of the locking rim 264 of the inking roller. The closing device 260 of the inking tube can now be removed without the inking tube 260 being held during this operation. The two halves X and Y of the casing of the apparatus can be connected by convenient locking With this obj ect in view a screw bolt Upon the an angle iron 10 with for a lead seal can be with an angle iron 24 (Fig. 7).

In order to avoid that for the adjusting of the locking devices 175-17 7 for the counting mechanisms the locking means 10, 11, 21, 22 have always to be unlocked and locked, a separate locking device is provided for these parts of the counter which consists of a cap 6 mounted in hinges 7 and having a locking bolt 61 and a lock 281 mounted on sockets 32 and 282. he cap 6 can be locked and unlocked gasi)ly by means of the lock 281 (Figs. 1,

A locking device can further be provided for preventing the use of the printing cylinder CZ, said device consisting either of a lid arranged over the recess d of the printing cylinder or of an envelope which encloses the printing cylinder partly or entirely, or the locking can be arranged as shown in Figs. l, 2, 3, 4, 7 and as will be hereinafter de: scribed.

The locking bow 302 position into part X of th'e casing screw 11 and lug l0 provided in connection on part Y of the casing projects at the lockinm the recess d of the printing cylinder d and embraces the latter the projection 297 of the guide screw 297 bearing against the angular locking piece 15 where it is secured by a padlock 15 or the like so that the bow 302 is secured in its locking position and the use of the printing cylinder d is prevented. If this device is unlocked the guide pin 297 is moved along the guide slot around pin 297 together with the angle piece 295 swinging around pin 297 so that it is in the openvposition. The T-shaped angle piece 295 moving thus along a curve, the arm which carries the guide stud 298 is lifted also in radial direction and in ascending'it forces the transmission lever 299 to followits movement. This transmission lever 299 which is connected with one of the supporting Walls 302 and is guided by the supporting lever 301 which is pivotally mounted upon it, raises also the supporting wall 302 and makes the locking bow pivot around the shafts 49, 80 so that it gets out of the locking position. The printing cylinder d is thus released for use. If the locking bow 302 returns from the open position into the locking position the movements of this locking device are repeated in reverse direction and with reverse effect.

At the front end as well as upon the side on which the adjusting lever 124 is mounted marks or hands 5 or 4 are arranged which indicate at which place of the surface to be printed the stamps have to be printed according to length or width so that the proper utilization of a determined surface to be printed is ensured.

In the machines of the ty e described which are electrically operatedp the date of printing the postage stamp, etc., are printed by a printing cylinder which has to be eX- changed each time a of another value has to be printed. Instead of this simple printing cylinder designed to print only one stamp value, the above described printing cylinder d for the printing of stamps of different values may be used alone or together with all the accessories.

The printing cylinder may also be arranged in front of an axle of a crank, the surface to be printed being conducted in the well known mannerbetween the two rollers.
